The Marines are built different, and I get that, so this probably nullifies my argument. This is probably where the Marines tell me to get fucked out of their AO.
Anywho, I still still struggle with a leadership position, at least at the Regimental level, that doesn't hold that Regiment's predominant MOS. Past that level? Sure. The smaller the unit, it is as much about leadership as it is nuance. That SgtMaj will understand their Marines a lot better if they are from the same community. They would, I'd like to think, be less likely to drop the hammer on a dumbass Lance Coolie if both are from the same world. As you get to the BN level, this becomes more important.
The same, but not, are situations where hospital management doesn't come from doctors or nurses. I've had IT directors who were MBA's, not nerds. If you're from a tribe/ community then you can appreciate and understand that community's problems better than an outsider regardless of rank. These are civilian examples, but I cannot believe this doesn't apply to every service.
The SgtMaj or whatever he was from Generation Kill raving about a "moos-tash" is a great example. Wasn't he from outside of Recon? Wouldn't a career Recon Marine approach the same topic from a different angle?
Eh, not my world and certainly something I can't change. Semper gumby, Marines. Keep doing what you do regardless of who is yelling at you for no damn reason at all.
